Are there piezoelectric force sensors for loads of about 150 tons ? 4

[LCform]

Hi All

I am looking for force sensors used for crank presses that work with a rate of 150-250 rpm and a force of 100-150 tons .So far I just found force sensors for maximum 50 tons , and I am not sure if these sensor can stand this working rate and if it's possible to dismantle and reuse them on other force conditions ?

Sounds like you need an indirect measurement method, either a cylinder (and use area ratios) or a leaver arm mechanism.

If I did my math correctly, there's:

don't know about their frequency response, though

I can do absolutely anything. I'm an expert!

For high forces in questionable environments either hydraulic load cells or strain gauges are cheaper than proper load cells. If you are in the linear range of your structure and it has a well defined load path even a single strain gauge will do at a pinch.
